An external co-processor is, effectively, a custom circuit. Therefore, I searched section 8 of the rules for things of that nature and found that <R66> and <R67> govern the input/output. According to the rules, then, it is legal provided that is connected as per said rules.

Given that the Axis camera is a sensor, you could indeed connect it to the custom circuit that is the co-processor under <R66>.

Please note that this is subject to change for next year.
